Charge Air Cooler


The charge air cooler lowers the high temperature resulting from the charging from about 140°C to 90°C and provides with it due to the better filling a higher performance and a better torque. In addition, the boost pressure can be raised by approx. 0.5 bar. If the higher performance is not used, a lower mileage is possible. Although it is inserted, in combination with the turbocharger, more often in the diesel engine, there is for the petrol engine an additional, important advantage. The cooled air lowers the temperature during the compression stroke. Therefore, the compression ratio does not have to be reduced as much in proportion to the normally aspired engine. The advantages singled out on top are greater for the petrol engine.

How it works

It works as an air-to-air heat exchanger and is inserted between loader and engine on the suction side. Throughout history there have been carburetor technologies featuring charge air coolers that were flown through by air-fuel mixture. Today it is only the air which is cooled down. If the charge air cooler is connected in series with the liquid radiator, like with utility vehicles, it must be arranged in front of this because it is important that the outlet temperature is lower. 05/08
